websocketthunderbirdthunderbird-addon

Is it possible to use WebSockets in Thunderbird addons?

It's definitely possible with Firefox but the same code is not working on Thunderbird.

Here is an example of what I am trying to do:

In my background.js:

console.log("a");

let ws = new WebSocket("wss://echo.websocket.org");

console.log("b");

But I only get this result in the debugging console:

Webconsole context has changed
a background.js:1:9
Webconsole context has changed
: background.js:3
    <anonyme> moz-extension://e908747f-c410-4427-8868-1336f813f1cd/background.js:3

I am testing on Thunderbird v68.6.0.

Solution

  • When I posted this issue, it was not possible to use WebSocket in Thunderbird.

    The bug is, at the moment I am typing this message, being resolved.

    Edit: The bug has been resolved since and WebSockets are available since Thunderbirg 77.0beta3
